94 2.5 engine pulsing?
My engine revs up and down while driving for about 30 seconds, then runs normal. This happens about every 5 - 10 minutes at random. It also idles normal.
All I need is 4 more inches.
My flat tow trail riding 98 TJ build

If you don't have any codes to point you in a course of action, then I would first look for vacuum leaks and then give the throttle body and IAC a good cleaning. Remove the TB and get a new mounting gasket. Clean the bore and IAC housing thoroughly with carb cleaner and see how she does.
